### Newton’s Laws

Newton’s First Law
• Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it.
• This law is often called "the law of inertia".
Newton’s First Law (Law of Inertia)
• An object at rest will remain at rest unless acted on by an unbalanced force.
• An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton’s First Law (Law of Inertia)
• This means that there is a natural tendency of objects to keep on doing what they're doing.
• All objects resist changes in their state of motion.
• In the absence of an unbalanced force, an object in motion will maintain this state of motion.

Newton’s Second Law
• The relationship between an object's mass m, its acceleration a, and the applied force F
• F = ma.
Newton’s Second Law
• Acceleration is produced when a force acts on a mass.
• The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
Newton’s Second Law
• What does this Mean?
Newton’s Second Law
• Everyone unconsciously knows the Second Law.
• Everyone knows that heavier objects require more force to move the same distance as lighter objects.
Newton’s Third Law
• For every action there is an equal and opposite reaction.
Newton’s Third Law
• What does this Mean?
Newton’s Third Law
• This means that for every force there is a reaction force that is equal in size, but opposite in direction.
• That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.
